Important! When accessing Revision History and 'Restoring a Previous Version', no changes are 'eliminated!' The selected version is simply moved to the top of the revision history panel. This is huge: it means that students can't inadvertently (or intentionally) remove edits that form the history of the collaborative document!

How might we shape that culture and how will we understand the many forces at work? Understanding the culture of class or perhaps even a school is an important element of our teaching but realising the complexity of this task must come first.

Blended learning, with its mix of technology and traditional face-to-face instruction, is a great approach.

Blended learning combines classroom learning with online learning, in which students can, in part, control the time, pace, and place of their learning. I advocate a teacher-designed blended learning model, in which teachers determine the combination that's right for them and their students.

Student-centered classrooms are the goal of my teacher-designed blended learning model. Giving students control over the learning process requires that they know how to communicate, collaborate, and solve problems in groups, pairs, and individually. This work can be messy, loud, and disorganized, but in the end, the learning is much more meaningful.

Then I found Collaborize Classroom, a free, dynamic discussion platform. I used it to replace many of my pen-and-paper homework assignments with vibrant online debates, discussions, writing assignments, and collaborative group work.

I anticipated that students might hit some bumps as they navigated their first TED-Ed lesson, so I set up a TodaysMeet back channel so students could ask questions, make comments, and access a support network while going through the online lesson. A back-channel tool makes it possible for people to have a real-time conversation online while a live presentation or real-time discussion is taking place.

I asked students to reference specific details to support their assertions, as did one student who commented on the town's poverty by noting that the local doctor often took potatoes as payment for his work. She also showed how the characters nevertheless reflected the country's "cautious optimism" about its future: That same doctor was still able to support himself, she pointed out, and he enjoyed his work. Students posted their responses, complimenting strong points made, asking questions, and offering alternative perspectives.

I asked students to analyze examples of strong discussion posts and revise weaker posts. I also realized that I needed to embed directions into our discussion topics to remind students to respond to the questions and engage with their peers. I started requiring them to thoughtfully reply to at least two classmates' posts, in addition to posting their own response to the topic.

For example, during the To Kill a Mockingbird unit, we researched and discussed the death penalty in preparation for writing an argument essay. The students debated online such issues as cost, morality, and racial inequality and then delved into these topics more deeply face-to-face in class.

In the classroom, the teacher might give small groups various topics to research. Then he or she could ask students to go online to research and discuss their topic on a shared Google Doc and create a presentation using Glogster, Prezi, or Google Presentation Maker.

When we read Romeo and Juliet, I use this strategy to encourage students to research such topics as the monarchy, entertainment, and gender roles in Elizabethan England so they have a better understanding of the historical context in which Shakespeare wrote. Back in the classroom, each group then presents its findings through an oral presentation.

Some teachers think that incorporating online work means they have to be available 24 hours a day. This is not the case. When students are connected online, they have a network of peers they can reach out to for support, and they begin to see one another as valuable resources in their class community.
